Injector Harness
Injector output wires need Female weather pack terminals crimped on. Below left side of photo is a 3
conductor connector used on each bank of cylinders on a 6cyl engine. 4 cylinder engines use 2 x 2
conductor Weatherpack plugs and look similar. Strip length is about 3/16 to ¼” for wires. Don’t forget to
install the red seals before you crimp the terminal. Right side of photo shows Male terminals and injector
harness wires will need to be crimped into these. Use position #2 on the crimp tool squeeze hard. Pull on
the wire to make sure the crimp is good and the wire does not pull out using about 10lbs pull force.
Look through the injector harness wires. Pick the longer length ones
for the cylinders farthest from your Weatherpack plug connection
point.
Injectors do not have polarity so either terminal on the injector can
be +12V or ECU output(minus).
One wire from each injector goes to a weatherpack connector, and
the other wire from each injector must go to 12V supply via a 5A
breaker. You will need to lengthen the injector wires destined for
+12V supply connectors and extra wire are not supplied for this so
splice long run wires back to your breaker panel & +12V.
